This topic provides step-by-step instructions for installing and configuring DataKeeper Standard Edition. The series of steps includes links into the documentation that describe each step in detail.

Prerequisites and Installation

  1. Read the SIOS Protection Suite for Windows Release Notes for late breaking information.
  2. Firewall Configurations – Make sure you understand what ports must be opened on any firewalls.
  3. Network Bandwidth – If replicating across a WAN, it is critical that a rate of change analysis be done to ensure there is adequate bandwidth.
  4. DataKeeper is a block-level volume replication solution and requires that each server have additional volume(s) (other than the system drive) that are the same size. Please review Volume Considerations for additional information regarding storage requirements.
  5. Review the section Understanding Replication to help understand how DataKeeper works and the difference between synchronous and asynchronous replication.
  6. During installation/upgrade, you will be prompted to select and set up a user account that will be used to start the DataKeeper Service. SIOS recommends using a domain account on each server (same account with the same password). This account must be added to each server’s local Administrator Group. Perform the following on each server:
    1. Select Edit Local Users and Groups
    2. Select Groups, Administrators
    3. Add the DK Service Account being used to this Administrator’s Group.

The following topics provide further information about these accounts.
